Hello All, After migrating my system (Fedora 20 x86_64) from a spinning disc on an old MB to an SSD on a new UEFI MB, I have problems starting any of my VirtualBox guest systems. The message I get says that either the kernel drivers are not installed or there is a permission problem with /etc/init.d/vboxdrv. I have run /etc/init.d/vboxdrv setup and that reports... Stopping VirtualBox kernel modules [ OK ] Uninstalling old VirtualBox DKMS kernel modules [ OK ] Trying to register the VirtualBox kernel modules using DKMS[ OK ] Starting VirtualBox kernel modules [FAILED] and sudo modprobe vboxdrv reports... modprobe: ERROR: could not insert 'vboxdrv': Required key not available so, does this mean that the problem is to do with a missing EFI boot key? Is there any way to fix this? Cheers, -- Regards, Terry Duell
